1 '0 all who/ii it may concern:

lie it known that l, llitllllihtrl lrhncizis, a

suih'ect of the Kin o'l .hhurland, residinir i '1 l i 'iiulicatinr; like mrts in the several figures This invention relates to u'uiel'iiues for insorting 'Fustenings and the gei'ieral object ol the invention is to provid-i an improved nuu-hine oi. this class es u-xcially adapted for use in the manu'lFacture oil boots and shoes.

'lhe invent ion. is herein shown as embodied in a machine oil. the type which inserts a plurality ot prcriously termed iastei'iings successively .in :l shoe to term a row, a machine (it this type l'ieingg' eiinnnonly kni'nvn as a loose nail inn; machine and conu u'isinp; usually a nail. driving mechanism, a raceway niecl'ianism 't'or coiuluctin r headed nails from a source of supply to a point adjacent to the driving! 1i'iechanism, a separator:lor cope rating the endnmst nail from the line (If nails in the rru-cni ay and delivering it to the driving mechanism, and an awl- :lor Forming successirely nail receiving opei'iing's in the shoe and harii'in ,iuinerally and preterahly the further :luuction of feeding the shoe hetween successive nail drirjingr opcrations.

in the iuanu'hicture oi" boots and shoes, it is Frequently desired in :ittncl'rinp; soles to shoes to drive a plurality oi? rows each comprising; sue sively inserted previously 'lm-nicd hciulcijl nails, such nailing whcn two rows of nails are inserted. hemp; con'inumly termed doulile row ruiilinp. Fastening insertii'ig machines have been designed for forming 'lustenings from a continuoi strip oi nuu-erial and insertinga plurality of rows oi those 'Iastcnings in a shoe. Also, heel attiu-hiiur machines have heei'i designed .i'or inserting a plurality ot rows oi? nails in the heel of a hoot or shoe. So tar as l. am aware, however. no unichine has heen proposed heretofore intended "For or capable of hen- (llinr, in bulk :uid inserting simultanooi[sly in the heel e1" a hoot or shoe a plurality of rows of? previously torincd 'lastenings, such,

tor example. as headed nails, to perform the hetero iucutieued double row nailing open ation upon a shoe. Consequently, before the present in vention it has always been necessary whenever it was desired to perform this operation first to insert one row of nails and subsequently to insert the second ron of nails. 7

One of the objects of the present invention is to provide a fastening inserting machine ee nihlc of inserting simultaneously in a shoe a plurality of rows of previously formed :l'astcnings when desired, thus avoiding the ex' 'ue iu ae and loss oil. time necessarily involvcdiu double row nailing as heretofore practised.

Inaecordance with this object ot the invention, in addition to mechanism for in.- sorting a plurality of fastenings successively inv a shoe to form a row, raceway mechanism tor supplyin r previously formed tastcnings to the inserting" mechanism and separator mechanism for governing the supply of fastcning's :lrom the raceway mechanism to the fastening inserting mechanism, the illus trated machine is provided with an auxiliary fastening inserting mechanism, Wherehy a plurality of rows each comprising successively inserted. fastening's may he insorted in a shoe simultaneously. In the emhiutliinent herein shown, the machine is pro-- vidod with auxiliary aw]. mechanism and auxiliary separator mechanism, as Well as zuiiz-ciliary driving mechanism, together with means for throwing the auxiliary and and separator mechanisms into and out of opera tion so that one or more rows of tastenings may be inserted at the Will oi. the operator. Preferably, and according to a feature oi. the invention, the construction and arrange ment are such that the auxiliary aw] and separator mechanisms may be thrown into and out of operation simultaneously. To this end, as shown, the operation of the auxiliary separator mechanism is controlled by the auxiliary awl mechanism so that When the auxiliary and mechanism is thrown into or out oi. operation, the operation of the auxiliary separator mechanism is thereby initiated or suspended.

it further Feature of the invention consists in autoi'natic mechanism Which insures that the auxiliary and and separator mech- :misrns can only be thrown into or out of operatioi'i at a proper point in the cycle of operations of the machine, In accord ance with this feature of the invention, provision is made for automatically locking the auxiliary aw]. and separator mechanisms against movement either into or out of operation while the shoe is being fed. For this purpose, the illustrated machine, is provided with a controller governing the initiation and suspension of the auxiliary awl and separator mechanisms and a locking member operated automatically upon shoe penetrate ing and movement to lock the controller and hold locked against further movement until the end of the. shoe fe ding movement, the controller being thereafter ,automath cally unlocked.

Other objects and features ofthe inven tion will be apparent from the following detaileddescription read in connection with the drawings.

The invention will be described as applied to a loose nailing machine of the. general type disclosed in United f'itutcs Letters Pat out No. 490,624, granted January 24,1893, on an applicationof LouisGoddu, to which Letters Patent reference may be had for dctaiied description and explanation of various features of theillustratcd machine not set forth fully herein. It is to be understood, however, tha it is recognized that the invention as a whole or various features thereof mayhave other. uses including use in loose nailinginachines of other types. In the following description the term nail will be used frequently instead. of fastening in describing the various mechanisms and the various operations performed by the machine, such use of the term nail being simply for convenienccand not by way of limitation.

Asis usualin machines of the type hereinbefoii e referredto, the illustrated machine, like the machine of said Letters Patent, is provided with a raceway adapted .to receive previously formed headed nails from ahcpper, a separator for separatingthe endmost nail from theline of nails inthe raceway and movable to present thenail. for the ope ation of a nailidriver, and. an awl having reciprocating movement to penetrate the shoe for forming successively nail receiving openings in the shoe and lateral movement to feed, the shoe between successive nail inserting operations of the driver. The awl, separator, nail throat and nail driver are carried by a swinging head which is operated after the awl' has been-moved downwardly to pierce the shoe to cause the awl to feed the WOTI. The awl is then raised out of the work and the swinging head is swung. reversely to carry the nail throat and nail. driver into positions over the nail receiving hole just made by the awl, after which the nail driver is operated to drive a nail into the said previously formed hole, the slice during the nail driving;operation heingiclamped between a work support on which it is mounted and a work plate secured to the machine frame. For a corn plete disclosure and description of the construction and operation of the before-mentioned parts of the machine reference should be had to saidlprior Letters Patent, since conveniently, andsas shown, these parts may be substantially like corresponding parts of the machine of said Letters Patent.

Refcrringto the drawings, the illustrated machii'iehas a supporting frame comprising a base, a standard or column 2 and a head 1st. in the head 14, as hereinbefore stated, are mounted the various parts of the fasteninserting, awl and separator mechanisms. V

Preferably, and as shown, to prevent clamaee to the parts of the machine, the machine is provided with means for prevent ing tl'irowin r the auxiliary and mechanism either into or out oi operation during a predet rmined part of the cycle ct operations oil. the machine. To this end the machine has a lochingr member 46 (Fig. 1) mounted :tor reciprocation in a slideway formed in. the upstanding; arm oi the elbow lever 4:0. The sliding locking member l6 is operated into locking; position by connections from the and mechanism operating shaft 35, a spring: 48 (Fig. 1) being mounted belon and partly within the locking member 46 to raise the locking member 4:6 to its normal inoperative position. when permitted. The connections from the movable locking}: member to to the and mechanism operating shaft 35., as shown and as fully set forth in United f 'ita' 7 Letters Patent No, 922,447, granted hlar 52 i, 3909, on an application of Bates and Gamble (see particularly Figs. 1 and f? o! said Letters Patent), comprise an arm 50 on the and operatiingg shaft and a ballended huh one end of which link proinn-ts into a recess 54-. termed in the upstandinn' big on arm 50 and bears against and is partlyinclosed in one end. of: a plug 56 in said recess 54, the plug; 56 having a shank tin-ended into a projection from said lug on said arm and being held in position by means of a nut 60. The other end. of the link 52is provided with a socket 62 adapted to receive a ball fit'forming the upper end of a screw 66 threaded into the locking member 4-6 and providing for adjustment of said locking member.

The locking member ltl carries a block 68 adjustably secured to said locking member by a screw 70, the said block having t vo notches or recesses 7 2 formed therein, one on each side. Pivoted to the frame of the machine is a stationary locking member 74 adjustable about its aivot by means of screws 76 which engage the stationary locking member 7 1 at either side of pivot and hold it firmly in adjusted position. The locking member 7a is also provided with an arm 7 8 having a bearing for one end of a ball-ended link 81, the other end of which link is seated within one end of a plug 80 secured in projection from the machine frame, the plug 80 assisting to hold the locking member 7a in adjusted position. To enable the stationary locking member 741 to cooperate with the movable locking member 46 to secure the elbow lever lO against movement when desired, the stationary locking member 7 caries on each side of the axis of its pivot a block 82, each of the blocks 82 having a tooth or knife edge, one or the other of which is received in the corresponding recess 7 2 in the block 69 upon downward operative movement of the movable locking member 46.

The construction and arrangement are such that the movable locking member 46 is automatically moved downwardly to cause one or the other of the knife edges projecting. from the block 82 on the stationary locking member 7a to enter the corresponding recess 7 2 in the block 68 on the said looking member 46 upon downward shoe penetrating awl movement. By this construotion and arrangement the elbow lever 10 is locked against movement either to connect or disconnect the awl mechanisms while a shoe is being fed. It will be understood that the position of the knee lever 40 when operative locking movement is imparted to the movable locking member to will determine which knife edge is caused to enter the corresponding recess, cue knife edge and recess cooperating to lock the elbow lever l0 when the elbow lever 1-0 is in the position in which the awl mechanisms are connected and the other knife edge and recess coopcrating when the elbow lever 40 is in position for elfecting disconnection of the awl mechanisms. Conveniently, stops 4:7 carried. by the machine frame are arranged to limit the movement of the elbow lever 40 in one or the other direction.

In addition to the driver mechanisms and. awl mechanisms before described, in order to adapt the machine for inserting simultaneously a plurality of rows of fastenings when desired, as previously mentioned the matching is provided with a plurality of raceway mechanisms for supplying previously formed headed nails and a plurality of nail separator mechanisms for governing the supply of nails from the'raceways.

For supplyin nails to the separators, the machine is provided with a raceway 84: and an auxiliary raceway 88 (Fig. 1) constructed and arranged to hold previously formed headed nails. The separator mechanisms comprise a separator 86 (Fig. 4.) and operating means therefor, and an auxiliary separator 90 and operating means for the auxiliary separator. The separator 86 is carried at the lower end of a lever 91 (Fig. 2) fulcrumed at 93 on the swinging head 14 and provided at its upper end with a roller 95 which bears against a cam face forming part of the cam disk indicated at 21. A suitable strong spring 97 attached to the swinging head it operates to maintain the roller 95 in engagement with its operating cam. As shown, the separator 86 is of a well-known construction and need not be described in detail herein, the described con struction and arrangement providing for reciprocating the separator 86 to cause its blade end to be inserted between the endmost nail in the line of nails in the raceway and the adjacent nail and to move said endmost nail to present it for the operation of its driver. The auxiliary separator 90 is carried at the lower end of a depending lever 92 (Fig. 1) pivoted at 94: to the swinging head 14.

In the illustrated machine. the auxiliary separator and the auxiliary awl mechanism are constructed and arranged to be controlled simultaneously, provision being made for causing initiation and suspension of the operation of the auxiliary separator to be controlled by the initiation and suspension of the operation of the auxiliary awl mechanism. To this end, the auxiliary separator lever 92 carries at its lower end a roller 96 adapted to engage a cam face 98 formed on the auxiliary awl bar 12, the construction and arrangement being such that when the auxiliary awl 10 is moved downwardly the cam face 98 will engage and swing the auxiliary separator lever 92 to move the auxiliary separator 90 into its retracted position in readiness to perform a nail separating operation. On the upward movement of the auxiliary awl 10 after it has pierced and fed the work, the auxiliary separator lever 92 will be swung forwardly again by means of a spring 100 and will be caused to separate and feed anail from its raceway. It will be apparent that when the auxiliary awl bar 12 is disconnected from the awl bar 16 and thereby rendered inoperative, the auxiliary separator lever 92 will also be rendered inoperative, As shown, the extrenio inn 'ard posititm ol the auxiliary separator lever (Fig. 1) may be varied by means of an adjusting screw 102 adapted to engage one face ol. the auxiliary awl bar 15!.

.llroin the foregoing description, it will be apparent that upon movement of the knee lever to operate the elbow lever one way r the other, the auxiliary owl and separator niecluinisins will thereby be rendered 'tlblitl operative or inoperative, and either one or two rows 01' nails will be driven at the will oi? the operator, movement of the elbow lever 1:0 to disconnect the auxiliary and bar 12 from the awl bar 16 operatiitig simultaneously to on use the operation olthe auxiliary separatcu' lever 92 to be Faispeuded, whereupon the machine will insert one row of: lastcnings only, the auxiliary driver 100 reciprocating idly.

the illustrated machine is provided with the usual work abutmentindicated at 108 (big. 1) and a roller 1.09 is introduced between the swinging head 1-l and the abutinent 108 to bear the upward thrust of the shoe and at the same time to allow the head 1-1; to swing to cause the shoe to be led. in the use ot the machine the work is sup ported upon a horn 13% between which and the abutment 108 the shoe clamped whenever a fastening to be inserted, asis usual in machines oi this type, the abutment 108 being provided with a hardened work plate 1532 which operates to press down any nails which may not have been driven flush with the shoe bottom. The inachii'ie is also providtvl with an edge guide 110 secured to a slide in the lraine of the machine and pro titled with an. upwardly extending portion lllha viiiig a cutaway part 116 into which projects one arm 118 of a lever iulcruined on the machine at 119, the other arm 120 of which lever forms a handle for the purpose ol moving the edge gage 110 into different adjusted positions. In the illustrated cons-itructiou the edge gage 110 is provided with a stop pin 1530 extended between two downwardly projecting lugs 122 formed on an ad ;'ustahle plate 127 secured to the frame of the machine by means oi." screws 128 passing through slots 130 toi'i'nediu said plate 127, As shown, the lugs 122 are spaced apart a distztnce equal to the distance betwemi the two rows of nails in and s (Fig. 0) lira-med when the machine is used for double row nailing for the purpose ortallowing the operator, if desired, to move the edge gage 1.10 quickly and conveniently to reuse the nail driver 10a to insert lasteir logs in the line oi. operation of the auxiliary nail driver 1.00 when only one row of taslrnings is to be inserted in a shoe.

in the use oil the illustrated machine, running that it is desired to drive simultaneously a double row of uails, the knee lover is first moved to connect the auxiliary and bar 152 to the awl bar 16' through the link 38 and lever 28, the connecting pin 2% thereby rendering the auxiliary awl 10 and the auxiliary separator 90 operative. Upon awl $1.0 (.lescends, thecain face 98 formed on i and bar 12 will swing the auxiliary separater-lever 952 and move the auxiliary sepaiator 00 into a position in readiness to separate thecildmost nail from the line oi nails in the auxiliary 'aceway 88. The head-1d then swings in a direction to cause the awls to feed the'work, the nail drivers and separaters being swung with the nude in a direction to :lieed theshoe. The shoe having been led, the awl bar 16 is theuraised, thereby withdrawiug the ends 10 and 10 from the shoe, the upward movement of the auxiliary awl bar 12 permitting the auxiliary separator lever 92 to be swung about its pivot 04: by the spring 100, thereby causing the auxiliary separator to perform a nail separating operation. Sinmltaneously with the nail separating movement of the auxiliary separator 90 the separator 86 delivers a nail from the raceway 84-.

Tllhe head 14: is then swung rcvcrsely to bring the drivers 10%, 106 into positions above the fastening receiving openings made by the awls. The work is then clamped in the usual manner between the work plate 132 and the horn 134:. There after, the nail drivers are forced down.- wardly by the spring 9 to drive simulta neously a pair of nails into the holes formed by the awls l0 and 12. As this cycle of operations of the machine repeated, two rows, each comprising successively inserted nails, are driven into the shoe simultie neously, the before described relatiw: positions of the awls and drivers being such that, as indicated in Fig. 9, the row oil. nails inserted by the auxiliary driverl06 is located farthcrtt'rom the edge of the shoe than the row of nails .2 inserted by the driver 104., the two rows being substantially parallel. By reason of the fact that the auxiliary and 10 and auxiliary driver 100 are located at one side ol the awl llland driver 10% respectively, the nails of the two rows and s are driven staggered, as shown in Fig. 9. Obviously, however, if desired the relative arrangei'nent of the rows :0 and :a-Wand the relative positions of the nails in. those rows may be varied readily by adjusting the relative positions of the awls and drivers.

While theshoe is being fed by the awls l0 and 18, the sliding locking member &6 will automatically be forced downwardly through its described connection with the aWl mechanism operatingshaft 35 to cause one of the notches 72 to overlap one of the teeth 82, thereby locking, the knee lever and elbow lever lO against movement, and thereby preventing movement of the pin 24. Upon subsequent upwardmovement of the awls after the completion of the shoe feeding movement, the movable locking, member 46 will be raised to its normal position'by its operating spring 48, unlocking the elbow lever 40 and knee lever and permitting manipulation thereof to connect or disconnect the and mechanisms, and thereby to render operative or inoperative the auxiliary separator mechanism.
